PCN's 18 best interviews on 'PA Books,' from scrapple to the mob

The hourlong television program features interviews with authors of books about Pennsylvania and has been showcasing the state's history, culture and people for more than 20 years.

On Sunday, PCN will televise episode number 800.

Who will be on the 800th episode?

The 800th episode will air at 7 p.m. and will feature author and musician Walt Koken. He focuses on "Old Time Music," traditional music handed down through generations of folk artists in West Virginia, North Carolina, Kentucky and Pennsylvania.

“The wonderful thing about Old Time Music,” says "PA Books" host Brian Lockman, “Is that it has a devoted audience who appreciate something out of the mainstream. Kind of like PCN viewers."

When "PA Books" premiered, it was only available on cable. Since then, PCN has launched PCN Select, where viewers can stream on-demand and new episodes for a subscription fee. You can sign up for membership here. The top 18 episodes will also be available through PCN Select.

"Hosting "PA Books" for the past 20 years has been more of a hobby than a job. It has offered me the privilege of spending an hour with hundreds of fascinating people who have written about Pennsylvania. And I hope it has enabled viewers learn something about their home state and, maybe, helped authors sell a few books," said Brian Lockman, PCN chief executive officer and president, said in a news release. "Whittling more than 20 years of PA Books down to my 18 favorites was a very difficult thing to do. It would have been easier to pick my favorite 100, but here goes in no particular order."
